Fix for: [pgpool-general: 4997] Avoiding downtime when pgpool changes require a restart
To fix this, The verification mechanism of configuration parameter values is
reversed, previously the standby nodes used to verify their parameter values
against the respective values on the master pgpool-II node and when the
inconsistency was found the FATAL error was thrown, now with this commit the
verification responsibility is delegated to the master pgpool-II node.
Now the master node will verify the configuration parameter values of each
joining standby node against its local values and will produce
a WARNING message instead of an error in case of a difference.
This way the nodes having the different configurations will also be allowed to
join the watchdog cluster and the user has to manually look out for the
configuration inconsistency warnings in the master pgpool-II log to avoid the
surprises at the time of pgpool-II master switch over.

Fixing a problem with the watchdog failover_command locking mechanism
From pgpool-II 3.5 watchdog was using the separate individual locks for each
node-failover command(failover, failback and follow-master) and the lock was
acquired just before executing the respective failover script and was released
as soon as the script execution finishes. This technique although was very
efficient but also had a problem. If the failover command takes a very little
time and gets finished before the lock request from other pgpool-II node
arrives, the other node is also granted a lock, since the lock was already
released by the first node at that time. Consequently, both nodes ends up
executing the failover script.
So to fix this we are reverting back to the tested failover interlocking design
used prior to pgpool-II 3.5 where all the commands gets locked at the failover
start by the node that becomes a lock-holder and each command lock is released
after its execution finishes. And only the lock-holder node is allowed to
acquire/release the individual command lock. That way the lock-holder node
keeps the lock-holder status throughout the span of the failover execution and
the system becomes less time sensitive.

Enhance performance of SELECT when lots of rows involved.
(From pgpool-hackers: 1784)
While taking care of bug track item 238:
http://www.pgpool.net/mantisbt/view.php?id=238
I found there's a room to enhance the performance of data transfer
from Pgpool-II to frontend. In an extreme case, such as sending many
rows to frontend, the enhancement was 47% to 62% according to my
benchmark result.
Currently Pgpool-II flushes data to network (calling write(2)) every
time it sends a row data ("Data Row" message) to frontend. For
example, if 10,000 rows needed to be transfer, 10,000 times write()s
are issued. This is pretty expensive. Since after repeating to send
row data, "Command Complete" message is sent, it's enough to issue a
write() with the command complete message. Also there are unnecessary
flushing are in handling the command complete message.
Attached patch tries to fix them. I did a quick benchmark on my laptop
(Ubuntu 14.04 LTS, 2 cores, 16GB mem, SSD) using pgbench (scale factor
= 1) + custom query (SELECT * FROM pgbench_accounts), with master
branch head and with patched version. The graph attached.
Unfortunately, performance in workloads where transferring few rows,
will not be enhanced since such rows are needed to flush to network
anyway.
